Seems like the cold shot is mostly going to affet the Midwest but the coastal East would still be warm

Right. It's strong enough to push across and the entire Eastern U.S feels it.
Here are the surface anomalies for April 4th from the GFS12z today
Here are the minimum temps from GFS12z for April 4th. I would say it wont be 'that' deep but maybe 20s to upstate North Carolina? Freeze Warnings would have to go out.

ACROSS THE CT RVR VLY RANGING DOWNWARD INTO THE U30S ACROSS EASTERN
MA INTO THE WORCESTER HILLS...THANKS TO LOW CLOUDS AND EAST WINDS
STREAMING OFF THE CHILLY OCEAN WATERS. ONCE BLYR COOLS WITH SUNSET
AND LOW LEVEL FLOW BECOMES SOUTHEAST...
BIG TEMP DIFFERENCES TONIGHT AS SHALLOW COOL MARITIME AIR BECOMES
TRAPPED ACROSS INTERIOR MA. TEMPS SHOULD REMAIN ABOVE FREEZING SO
NOT EXPECTING ANY FREEZING RAIN/DRIZZLE. THEN ACROSS CT-RI AND
SOUTHEAST MA WARM SECTOR OVERSPREADS THE REGION TOWARD MORNING WITH
TEMPS JUMPING INTO THE 50S. GIVEN THIS WARM FRONTAL BOUNDARY WILL BE
LIFTING NORTH INTO THE REGION ALONG WITH SHALLOW COOL AIR TRAPPED
ACROSS THE INTERIOR...TEMPS TONIGHT WERE DERIVED FROM THE HI RES

STATIONARY FRONT JUST SOUTH OF AREA ACROSS CENTRAL NJ...PRECEDED
BY A STRATUS BANK ACROSS MUCH OF LONG ISLAND...NYC METRO...AND
COASTAL CT WILL ADVANCE NORTH AS A WARM FRONT THIS EVENING.

Strong storms in northeastern Broward, Palm Beach, Central FL and North FL......of course avoiding Dade and south Broward like AIDS thunderstorm hole season has started yet again....
The teens for you or the depth of it? 10 days out so I would say 30% chance its wrong? because Ensembles support it and so does the Euro. So there is support. Along with other tellies and stuff. But there's always a chance it wont be as deep a cold. There wont be a Hot ridge for that time period, that's for sure.

So the Upper Level winds are from the SW and even the mid level winds so its pretty interesting to see the cold up there hanging on....
Reason for their cold is the winds at the surface AND Check out the 850mb temps. Below freezing over Maine +11C over Buffalo
Surface Map. High Pressure near the Hudson Bay feeding cold air down to Maine and also creating resistance for the warm front over NJ I think.
